This contribution describes a new kind of ranging system based on a recently developed optical sensor called the Photonic Mixer Device (PMD). This new device combines fast optical sensing and modulation of incoherent light signals in one component part by its unique and powerful principle of operation. Due to this, the device is blind for any kind of uncorrelated light. An line or array of these smart sensors provides a multi-dimensional ranging system as will be shown in our contribution. We propose the advantages of this new approach, including the useful qualities of using a PN-code sequence. Especially the results of the extremely high resolution ranging system, including a new kind of PMD elements, are the main focus of this contribution.
